Why?
1. because altcoin season is not here.
2. because miners are still selling cheap Litecoins from past mining.
If halving as going to have any effect on the value of Litecoin, you would have known by now, but since there is nothing, then don’t expect anything from it again, that factor is already gone and we need to move on with our lives. Altcoins season generally is what makes most altcoins increase in value and Litecoin will surely be among coins that will be considered for investors being that it has its own popularity too to some extent.
